Abstract

A pump 24 with speed control is utilized. A dispenser 12 may have a trigger 16 which actuates a valve 16. Dispenser control 18 has "up" and "down" buttons, 20 and 22 respectively. The controls 28 (comprising elements 18, 20 and 22) for the pump 24 are remote from pump 24. The controls communicate with the pump via wires or radio frequency (RF) 26 to regulate pump speed. Quick button (20 and 22) presses will incrementally change the flow setting while long button (20 and 22) presses will change the settings at a higher rate. This control method can also be tied to the controls located on the pump 24. The potentiometer 30 on the pump 24 will set a max setting, and any adjustments at the valve can go below this setting and back up to it, but never exceed it.

Description

ADJUSTING PUMP FLOW AT TOOL
TECHNICAL FIELD
This application claims the benefit of US Application serial number 61/315,322, filed March 18, 2010, the contents of which are hereby incorporated by reference.
BACKGROUND ART
DISCLOSURE OF THE INVENTION
It is an object of this invention to be able to adjust pump speed from a location remote from the pump. Such pumps may typically be used for applying fluids such as paints and coatings as well as more viscous materials such as drywall mud.
A pump with speed control is required. The controls for the pump are remote from pump. The controls communicate with the pump via wires or radio frequency (RF) to regulate pump speed. Quick button presses will incrementally change the flow setting while long button presses will change the settings at a higher rate. This control method can also be tied to the controls located on the pump. The potentiometer on the pump will set a max setting, and any adjustments at the valve can go below this setting and back up to it, but never exceed it.
It is an advantage of this invention that there is no need to walk back to the pump to set the pump speed.
These and other objects and advantages of the invention will appear more fully from the following description made in conjunction with the accompanying drawings wherein like reference characters refer to the same or similar parts throughout the several views.
BRIEF DESCRIPTION OF DRAWINGS
Figure 1 shows a cross-section of a dispensing device utilizing the instant invention wired or wirelessly connected to a controlled pump.
BEST MODE FOR CARRYING OUT THE INVENTION
It is an object of this invention, generally 10 to be able to adjust pump 24 speed from a location remote from the pump 24. Such pumps may typically be used for applying paints and coatings as well as more viscous materials such as drywall mud.
A pump 24 with speed control is utilized. A dispenser 12 may have a trigger 16 which actuates a valve 16. Dispenser control 18 has "up" and "down" buttons, 20 and 22 respectively. The controls 28 (comprising elements 18, 20 and 22) for the pump 24 are remote from pump 24. The controls communicate with the pump via wires or radio frequency (RF) 26 to regulate pump speed. Quick button (20 and 22) presses will incrementally change the flow setting while long button (20 and 22) presses will change the settings at a higher rate.
This control method can also be tied to the controls located on the pump 24. The potentiometer 30 on the pump 24 will set a max setting, and any adjustments at the valve can go below this setting and back up to it, but never exceed it.
It is an advantage of this invention that there is no need to walk back to the pump to set the pump speed.
It is contemplated that various changes and modifications may be made to the control system without departing from the spirit and scope of the invention as defined by the following claims.

Claims

1. A fluid dispensing system comprising: a pump having a speed control; and a dispensing device, said device having at least first and second controls capable of communicating with said pump, one of said controls actuable to increase the speed of said pump and the other of said controls actuable to decrease the speed of said pump.
2. The fluid dispensing system of claim 1 wherein said pump comprises a potentiometer setting the maximum speed of said pump such that said controls may increase and decrease said pump sped but no higher than said maximum.
3. The fluid dispensing system of claim 1 wherein quick presses of said controls incrementally change the speed setting while long control presses will change the settings at a higher rate.
